ACETYLENE-GAS'GENERATOR.

SPECIFICATION forming part of LettersfPatent No. 701,598, dated June 3, 1902. Application filed January 2,1901. Serial No. 41,923. (llo model.)

T0 all whom if may concern,.-

Beit known that I, JOHN A. MosHER, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements'iu Acetylene-Generators,of whichV the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof. f

This invention relates to that type of gen erators in which a removable generating-cell is employed, which is adapted to be attached to the nipple of water-feed and gas-distributing piping systems; and the object of the invention is to provide means for venting the cell should the valve of the nipple be closed'so as to cut oif the water-supply and the gaspipe, so that should any generation. occur, dueto the presence of moisture within the cell, the gas may be carried off without necessitating its discharge through a safetyvalve. This object is accomplished by the construction hereinafter described,and which is illustrated in the accompanying drawings, in which r Figure 1 is a detail front elevation `of a pair of generators. Fig. A2 is a detail plan section on the line 2 2 ofFig. 1, and Fig. 3 is a detail section on the line 3 3 of Fig. 2.

The generating-cells 5 6 are adapted to rest upon the chairs 7 8 and to engage by their nipples the nipples 9 10 of the water-feed and gas-distributing piping systems. Water is led to these cells by the pipes 11 and 12 and gas is conveyed therefrom by the pipes 13'14, which ultimately discharge into a common gas-distributing pipe 15. Water-reservoirs are shown at 16 and 17, and water is conveyed therefrom to the pipes 11 and 12 by the pipes 18 and 19, respectively. There is direct connection between the pipes 11 and 12 andthe nipples 9 and 10 by means of the pipe-sections 2O 2O and indirect connection therewiththrough the loops 21 22, leading upwardly from the pipes 11 and 12 and returning to the pipesections 20. A three-way cock is located at the end of the return-arm of'each of these loops, so as to control both the direct connection 20 and the loop connection 21, this valve being adapted to provide either a diboth. Asshown, the loop is open at the same time as the direct connection through the pipe 20. This is entirely immaterial, as the water will of course make its entry through the direct connection rather than through the loop, if possible. A three-way cock 24 is located in each of the nipples 9 and 10, so as to simultaneously open and close the pipes 2O and the pipes 13 or 14.

None of the features thus far described are new in this case.

The new feature of the generator consists in the vent-pipes 25 26, leading from the nipples 9 10 below the cocks 24 and each extending upwardly as a loop above the reservoirs 16 and 17 and returning enter the water-supply pipe, preferably at the loops 21 22 as shown. Should the cocks 24 or either of them be closed while the cell connected with the nipple in which such valve is located remains open and should there be any moisture present in such cell, any gas which may be generated will find its escape through the Vvent-pipes 25 26, and if the generation is sufiicient to develop a pressure exceeding the head of water it will force the water back through the pipes and escape into the waterreservoirs, as in the case of any excess of pressure. Y

I claim as my invention- 1. In an acetylene-generator, Ain combinavtion,watersupply and gas-distributing pipes,
